Specification of Letters Patent.

Patented Jan. 14, 1913.

Application filed June 1, 1911. Serial No. 630,556.

To all whom, it may concern Be it known that I, ALFRED A. CASSIDY, acitizen of the United States, residing at Minneapolis, in the county ofHennepin' and State of Minnesota, have invented a new and usefulDispenser, of which the following is a specification.

The device forming the subject matter of this application, is adapted tobe employed for delivering predetermined quantities of material from asupply tank, into receptacles of various sorts.

It is the object of the invention to provide a novel means forelevatingthe contents of the tank, and for discharging the contents ofthe tank, in varying quantities, into a conductor, which, in its turn,discharges into the receptacle which is to be filled.

A further object of the invention is to provide a device of thecharacter above specified, in which the conducting member whichdischarges into the receptacle which is to be filled, constitutes ameans for mounting the container, whereby predetermined quantities ofliquid, are elevated, and dis-.

charge into the conductor. I

A further object of the invention is to provide novel means forproducing relative movement between the container and the conductor, andto provide novel means whereby the operator may set the mechanism todeliver different quantities.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides inthe combination andarrangement ofparts and in the details of construction hereinafter.described and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departin from the spirit of the invention.

In t e accompanying drawing s, -Figure 1 shows the invention in endelevation; Fig. 2 is a vertical section upon the line A-B of Fig. 1;Fig. 3 is a vertical section on the line OD of Fig. 2; and Fig. 4 is adetail perspective showing a portion of the operating mechanism, and themeans whereby said portion of the operating mechanism is regulated andadjusted, so that the device may deliver predetermined, differentquantities.

In carrying out the invention there is pro vided, as a primary element,a tank, denoted generally by the numeral ,1, the tank being suitablysupported upon legs 2, or-in any other desired manner. The tank may beof any form. Preferably, however, as shown, the tank is equipped,adjacent its front, with a depending extension 3. 0

The tank 1 may be of any length, so that any desired number ofreceptacles'may be filled simultaneously. With thisend in view, theinvention comprises a plurality of delivery mechanisms, three of thesemecha- 5 nisms being shown. These several delivery mechanismsare'duplicates of each other, andv but one of them will be described, itbeing understood without further explanation, that this description willapply with equal propriety, to all of the delivery mechanismsl Infashioning each delivery mechanism, then, a .conductor is provided,through which the liquid in the tank 1 may pass into the receptacle 1which is to be filled. This conductor takes the form of a tube 5, theupper end of which upstands above the upper edge of the tank 1, thelower end of the tube 5 being carried downwardly through the bottom ofthe extension 3 of the tank. In the tube 5 relatively near to the top ofthe tube, but well within the contour of the tank 1, is an opening 6.

The tube 5 extends through the bottom of -a container 7, preferably ofcylindrical form,

the container 7 being open at the top. Secured to the top of thecontainer 7 is a bridge piece 8, through which the tube 5 extends. Theconstruction, therefore, is such that the container 7 is mounted formovement in a right line upon the tube 5.

vMechanism is provided for raising and lowering the container 7. Infashioning this -mechan1sm, bearings 9 are secured to the ends of thetank 1, and in these bearings, is journaled for rotation a shaft 10.Secured to the shaft 10 are a plurality of bifurcated crank arms 11, andthrough each of the crank arms 11 is extended an arched link 12,

the-lower ends of the link 12 being pivotally engaged with the ends ofthe yoke 14, se cured to the bridge piece 8. To one end ofthe shaft 10,uponthe outside of the tank 1, an arm 15 is secured, the same having anoutstanding handle 16. From the foregoing it willbe seen that bymanipulating the handle 16, the container 7 may be reciprocated upon thetube 5.

A means is provided whereby the lifting v movement of the container 7may be regulated, so that the container will discharge difierent,predetermined quantities into the tube 5. With this end in view, thescale 17, suitably graduated to indicate diderent units of volume, ismounted upon one end of the tank 1, inthe vicinity of the arm 15, thearm being adapted to register upon the successive graduations of thescale 17. Secured to the tank 1 in the vicinity of the scale 17, is abracket 18, upon which is mounted, slidably, a stop 19. The stop 19 isheld in place upon the bracket 18 by a set screw 20. The stop 19 may bepositioned adjacent any of the graduations of the scale 17, and when thearm 15 is swung about, the

, arm will come into contact with the stop 19.

At this point it maybe stated that the form of the stop, and the mannerof mounting the same may be varied, it being necessary merely, that somesuitable means be provided, whereby the handle 15 may be arrested in itsmovement, opposite to each and all of the graduations upon the scale 17.

The operation of the device is as follows: The tank 1 is filled with theliquid to be dispensed, to a level slightly below the openings 6 in thetubes 5, as shown in Fig. 3. The set screw 20 is loosened, and the stop19 is slid upon the bracket 18, until the stop 19 is positioned oppositethe desired graduation upon the scale 17, the particular graduationreferred to, representing the volume of liquid which is to be deliveredinto each of the receptacles 4. By manipulating the set screw 20, thestop 19 may be held in its adjusted position. The receptacles 4 arepositioned below the lower ends of the tubes 5, the containers 7 restingupon the bottom of the extension 3 of the tank, the upper ends of thecontainers 7 being well below the level of the liquid in the tank, sothat the containers will be filled with liquid. The handle 16 is nowseized, and the arm 15 is swung about, causing a rotation of the shaft10, and a consequent lifting of the free ends of the crank arms 11, thearms 11 elevating the links 12 which are pivotally carried by the arms,the links 12, in their turn, through the instrumentality of the yokes14: and the bridge pieces 8, elevating all of the containers 7simultaneously, the containers slid ing upwardly upon the tubes 5. Whenthe containers 7 are thus elevated, their upper edges will be raisedabove the openings 6, so that the liquid which is in the containers 7,will flow through the openings 6, and thence downwardly through thetubes 5 into the receptacles 4:, the liquid thus continuing to flow intothe receptacles, until the mem bers 7 are drained to the level of theopenings 6 in the tubes 5. When the arm 15 is swung about, to cause arotation of the shaft 19, the arm 15 will come into contact with the etc19. This stop 19, as has been pointed out eretofore, will have beenpreviously set, to indicate a given volume. The engagement between thestop 19 and the arm 15 will permit the containers 7 to be elevated tosuch an extent only,- that the predetermined quantity of liquid willflow through the openings 6, it being obvious that the nearer theopenings 6 are to the bottom of the container 7, the greater will bethevolume of liquid delivered into the receptacles 1. Owing to the factthat the openings 6 are fashioned in the tubes 5, it is not necessary toelevate the containers 7 until the bridges 8 are above the upper ends ofthe tubes 5, in order that the containers 7 may discharge into thetubes. The bridges 8, therefore, are made effective, throughout theentire stroke of each container, to regulate the sliding movement of thecontainer. Moreover, the openings 6 serve to maintain the liquid levelbelow the crank arms 11, which operate within the tank.

From the foregoing it will be seen that by simply manipulating the arm15, a large number of receptacles may be filled, or partially filled.simultaneously, with a given volume of liquid.

The device is adapted to be employed for filling bottles, large gasolenecans, and receptacles of any other sort, the contents of,

which must be measured. I

Having thus described the inventlon what is claimed is A device of theclass described comprising a tank having a dependin extension; a shaftjournaled upon the tan an arm secured to the shaft; a link connectedwith the arm; a tube protruding through the bot-- tom of the extension;a container slidable upon the tube; and a single element constituting atonce a guide for the container and a place of attachment for the link,said element consisting of a bridge secured across the top of thecontainer and slidable upon the tube, the bridge having means forpivotally receiving the link; there be1ng an opening in the tube,through which opening the container is adapted to discharge, the freeend of the arm being above the opening, when the container rests uponthe bottom of the extension.

In testimony that 1 claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
